When these sensors provide conflicting data, it can lead to various issues within the vehicle's cooling system.
Common Causes of P00B6
- Faulty radiator coolant temperature sensor
- Faulty engine coolant temperature sensor
- Wiring issues or poor connections
- ECM malfunction
- Coolant system leaks or low coolant levels
Symptoms of P00B6
- Check engine light illuminated on the dashboard
- Engine running hotter or colder than usual
- Poor fuel efficiency
- Engine misfires
